I plug my iPhone into my computer to charge and to back up the data. Sometimes when I do this a message pops up on the system tray, saying that the device was not properly installed and then my keyboard and mouse will not work and I usually have to restart my computer to resolve the issue. My keyboard and mouse are each USB devices as well.
Though sometimes I can plug my iPhone in and everything works just fine.

Why does this happen, any ideas?

Thanks in advance.

Go Start, right click the My Computer entry, click properties, click hardware, click device manager go to USB Controllers, expand it and then go to USB Root hub and on the power management tab ensure that - allow windows to turn off is NOT checked.
See my screenshot.
Although uSB devices are hot pluggable, they should not be dieconnected without stopping the device if that applies which I think it will do in the case of your iphone. Go task bar Safely remove hardware and double click that icon then expand to your phone and click stop. then when it tells you that the hardware can be safely reomved do so.

Try this please and post results.

I currently have seven USB Root Hub's in my list, do I need to uncheck the "Allow the computer to turn off this device to save power" box in each of these?

Device Manager>>Double Click one of the Root Hub entries>>
click the Power tab

attached devices will be listed there

If you are in doubt just enable them all

See how it goes. If it is OK in a day or do would you please return and mark the thread solved. You can always post again if afterwards you have a problem.
If you HAVE not been applying safely removed hardware - may I advise you to do so.
All sorts of problems are caused by not following that procedure.
Not least of these is the risk of data corrruption on the device.

I have just realised that you have presumably been forcing a shut down by disconnecting the power, when your keyboard and mouse have frozen.
If this is the case, please run chkdsk /f from a cmd prompt or using the GUI run chkdsk - on automatically fix file system errors.

After you have done that run system file checker pls.
that is "sfc /scannow" without quotes at run - on start menu

Did chkdsk find any errors of note and have you run system file checker.

Turns out it is still giving me some issues, I have ensured that the "Allow the computer to turn off this device to save power" is still unchecked.

What else should I look at?
